Numerical calculation of 3D equations in gas dynamics is examined. Equations are derived for mixed coordinates where some coordinate lines are Lagrangian and others are Eulerian. A difference scheme is given for a particular coordinate system with two Lagrangian and one Eulerian directions which was obtained from an original Cartesian system. Numerical results of 3D perturbation evolution calculations are discussed for the RayieighTaylor instabiIity.
